4.5.3 Permanent Tare Weighing
In this mode, the known tare weight for a vehicle is stored in the Permanent ID table, making one-pass weighing
possible. When the full vehicle is on the weighing platform, the stored tare weight is recalled from memory by ID
and an outbound process triggered.
New Permanent ID records can be created either by direct entry in setup or with an initial stored tare weight of zero.
During the first transaction involving this vehicle, it will be weighed twice, once empty and once full, and the actual
tare weight determined and updated to the record.
The Permanent ID table can be configured to accumulate total weights for trucks in a fleet of known vehicles.
4.5.4 Operational Features
In addition to the fundamental weighing functions, the following T72XW indicator basic weighing features can also
be used within the Vehicle Weighing application.
ID Entry
If an ID value is entered in the basic weighing mode, it remains available for printing when in the Vehicle application.
However, within the Vehicle application the ID function is used only to retrieve records from the Permanent ID table
or the Temporary ID table.
Net Sign Correction
When enabled (in setup at Scale > Tare > Types), Net Sign Correction allows the T72XW to be used for both
shipping (inbound empty) and receiving (inbound loaded) operations and always display a positive net weight. If net
sign correction is disabled in setup, any stored weight value in the tare register is assumed to be a tare regardless
of the gross weight present on the scale at the time of the final transaction. In this case, if the stored weight is
actually the gross weight, the net value can be negative.
With net sign correction enabled, if the stored weight is larger than the weight on the scale, the indicator will treat
the larger weight as the gross weight and the smaller weight as the tare weight, so that the difference will always
result in a positive net weight.
4.5.5 Configuration
The FUNCTION key must be programmed for Vehicle Weighing in setup at Application > Function Key >
Assignment in order for this application to operate and to access the setup steps for the Vehicle Weighing
application. When the FUNCTION key is properly programmed, the Vehicle Weighing branch of setup is displayed
as shown in Figure 4-18.
